WP Regular post categories bug also affects Woocommerce products categories

i have found a bug that is causing me lot of frustration when doing menus using categories.

There is a bug with the categories nesting/child categories on the menu create page. When having many sub-nesting/child categories when the category list has over 50 nested categories and the category small menu auto creates a second page then it messes up the categories nesting.

This is hard to explain.

On this 1st image, is when some sub-nesting/child categories fit on one page. this is good.
Note:I had to remove the menu box height to show what i mean.

but when a sub-nesting/child categories have too many sub-nesting/child (about 50) that gets chopped on 2 or more pages then the tree of the categories then the tree bugs.

This is Tab/page:2
It brakes the tree here too plus it adds the rest of the sub-nesting/child categories at the bottom of the page why? it should be at the top as its the continuing of tab/page 1 of the categories.

This bugs also affects Woocommerce products categories as we sometimes need many sub products categories.

i 1st found this bug when doing a menu with Woocommerce products categories i opened a bug report here:

here or some screen shots of that bug ticket.

After talking with some Woocommerce devs they told me this was a WP core bug.

i note "It looks like the problem has to do with the nesting / child categories. The second page starts with the categories that are top-level and their children. Then at the end it has the miscellaneous categories whose parents are on page 1."

" But it's not something we should be fixing as it's generated and rendered by WP core (all hierarchical categories output in the same way). We don't control that code."

"If that's broken because of WP core's handling (looks like it is), yeah I think we should raise it."

So this is why i am opening this ticket with WP.

How to replicate this bug with WP.
create a root Categorie with 2 or more Parent Categories in it.
then add say 50 subcategories in a parent so on the create menu page the category menu box splits the subcategories on a second page. Note: it needs to split the subcategories. if the subcategories fits on one page it will not work)


root cat 1
root cat 2
root cat 3
          - Parent Lv 1
          -- Parent lv 2
          ---  Parent lv 3 - category 01
          --- (ADD 50 other category in this parent)

To replicate with WP categories, add > 50 top level categories to trigger pagination on the menus screen.

Then give the term a few up from the bottom of page 1 several children.

Nesting is lost/terms are ordered wrongly.

Gets even weirder when lots of top level categories have children.
